Grit and sediments in your water mains lead to mechanical failures and increased wear and tear on your mechanical systems. Removing those sediments with a fully automatic strainer provides up to a 75% reduction in regular mechanical maintenance, overnight.
The Profimat is installed on your domestic water main as it enters your building. The water flows through the unit and its integrated 100 micron stainless steel screen removes sediments, grit, rust, sand, sludge and turbidity.
When the screen starts to get dirty, the entire filter surface is then automatically backwashed by multiple jet nozzles that operate on a point-by-point rotation system. The backwashing is completely visible at all times so you get real-time feedback on performance.
The backwash is intiated by an adjustable pressure differential switch (1-10psi) which senses plugging, and an adjustable timer (or a manual button press).
The backwash process uses very little waste water but provides a thorough cleaning of the screen with mimimal pressure loss or water wasted. Filtered water is constantly supplied past the unit with no interruption, even during backwash.
Due to the massive reduction in regular mechanical maintenance and the environmental benefits of this system, Europe has legislated cleanable strainers at the point of entry to all types of buildings. North America has yet to mandate this type of protection, but the good news for you is that retrofits are easy.
The three most common applications are point-of-entry, cooling towers, and rainwater harvesting systems (after the booster pumps).
Profimat strainers should be installed in every building at the point of entry. The return on investment due to the reduction in regular mechanical maintenance is often staggering (pumps, boilers, flushometers, cooling towers, PRVs, seals, fittings, pipe, filters, heat exchangers, nozzles, backflows, faucets, etc).
